`means for 4locking the door of the journal box in order to prevent persons from wrongfully removing the brasse: or waste which is frequently done by improper persons resulting in injury to the journals or even Wrecking the train. The wrongful removal of the brasses or waste is usually done while the car-or cars are detached and upon a siding.

A further object of my invention is 'to provide means for automatically locking the journal box doors as they are closed, and to provide an automatic flocking device which can be unfastened only when coupled to the compressed air system of the train or when in the shop, and that by the trainmen or other employees of the road -provided with necessary coupling device.

A further object of my invention, is to provide a lock as mentioned, which shall be of simple construction und' which may be readily applied to the door ot' any ordinary journal box. i

Other objects will appear hereinafter.

My invention will be more readily understoo by reference to the accompanying drawings forming a part of this specilica tion, and in whic j Figure 1 is a verticallongitudinal section through the frontend of a'journal box illustraining the vdoor equipped with a looking device ernbodying my invention, Fig. 2 is a transverse section of the box on the line w-w of Fig. 1, Fig. 3 is a section of the doorfon substantially the line yy of Fig.- 2, Fig. 4 is a detail section sunilar to Fig. 3 illustrating the device for 'unlocking the door in position, and Fig. 5 is a section of the lool; on the line. e-e of Fig. 3 and upon an enlarged scale.

Referrlng to 'the drawings 1 indicates a journal box of any ordinarv or preferred construction, 2 thedoor, 3 the journal and 4 the brass.

5 indicates the usual waste arranged within the box to keep the journal roperly lubricated. These portions of the evlce are old and @Amay be of any preferred construction and county ofCook, and State of Illiwith a single unloc in the drawings I have illustrated an M. G. B. journal box.

1n carrying out my invention, I provide a spring latch or bolt arranged upon the inner faceof the door 2 and arrange the same so that 1t can only be opened by compressed air, hence pcrsons cannot improperly open the door an remove the brass or waste. A1- though one latch may be 'employed u on each door, I prefer to rovide two so t at if one refuses to work, tie other will secure the door in closed position. These I equip ring device.

Referrinfr now to the drawings 6 indicates a plate havin r a plurality of holes 'i' for the rivets 8 by w iich it is secured to the inner face ofthe door 2. Arraneed upon the plate are a pair of spring latc es or bolts 9--9 vhaving -the parallel stems 10--10 arranged in a casina' 11 formed integrally with the plate 6. 'I`l1e casing is provided with the recesses. 12 to receive the bolts and their stems, and the recesses terminate in the reduced portion or bores A13 to receive Vthe upper end of the stems, formin the shoulders 14 between which, and the s loulders 15 on the bolts 9 are interposed `the springs 16. The inner edge or faces of the bolts 9 are beveled or curved as at 1T to engage thelip 18 of the box as the door is closed. It is obvious that when the doors are closed, the spring pressed bolts 9 automatically lock the saine in closed position. The upper lends of the stems 10a-re connected by a lilik or bar 19 which extends through slots 20 in the walls 21 of the bores 13 and into recesses 22 in the upper ends of the stems. It is evident that by raising the bar 19, the latches 9 will be raised vto unlock the door. Arranged centrally between the recesses `12 and in the casing 11 is a cylinder or cyli'ndrical bore 23 'in which 4is arranged a piston 24 having a stem V25 extending vertically unward and inipinginv against the undere ge of the bar 19 at substantially its central point. The cylinder .23 and the stem 25 are arallel with the stems 10 of the -latches or olts. Y 26 indicates a plu closing .the upper end of the cylinder and etween which and the piston is arranged a sp'ri'n 27 which normally keeps the piston and its stem in lower or depressed position. 28 indicates a lug on the bottom of the piston to limlt the same Vin its downward movement. This also limits the downward movement of the bolts.

V unlocked.

arranged upon the outer face ofthe door of The plate 6 is provided with a sleeve 29 which extends through the door 2, the door being drilled to .receive the same and said sleeve is provided with a passa eway 30 which extends beneath the piston 4. It is te prevent the piston from closin the port 31 of the passageway that the ug 28 is provided. By admitting air under pressure throu h the assageway `30, the piston 24 is raise unlocging the door and this is the only manner in which the door may be 32 indicates a hinged closure the passageway 30. The compressed air necessary for unlocking the door may be readily supplied from a compressed system of a train or at the shops where the car may be taken for repairs, .but it, is obvious that it is practically impossible to supply the necessary air to the device whcnvdetached and u on a. siding, hence the door cannot be opened) at such times.

33 indicates a flexible pipe or hose havin the coupling 34 by which it may be attache to the train pi es or other source of compressed air. T e opposite 'end of the hose 1s provided with anozzle 35 having a stop cock 36.V To unlock the door, the hose 1s coupled to the train pipe and the nozzle 35 inserted in the passageway 30'after which, the stop cock 36 is opened. This raises the piston 24 which in thel manner heforedescribed, raises the latches and unlocks the door.

3T indicate apertures in the plug 26 for maintaining constant atmospheric rassure on the upper face of the piston. T e apertures 37 also permit the escape of any air which passes by the piston 24.

38 indicates a sleeve tapped through the 1. A journal box and the usual door in combination with a pair of spring pressed bolts arranved u on the inner face of the doorand adapte to automatically lock said door as the saine is closed, a bar connectingls saidbolts, a piston arranged beneath sai bar and having a stein im inging against the lower edge thereof andpnieans for admitting compressed air beneath said piston, substantially as described.

2. A journal box and the usual door in combination with a pair of spring pressed bolts arran ed upon theinner face of the door and axipted to automatically locksaid door as the same is closed, a bar connectn said bolts, a piston arranged beneath said bar and having a stem `impinging against the lower edge thereof, means for admittin compressed air beneath said piston ancgl means for maintaining constant atmos heric pressure upon the upper face thereo substantially as described.

In testimony whereof I have signed my name to this specication in the presence of two subscribing witnesses.
